Attrition is a major factor, but skill level may also have a play for some, take me for example, dispite being a member for several years, my skill level and knowledge is not that high. never realized what the sss was capable of thus I did not enter the road contest. but this is a defect easily fixed. a review of the notes Dune kindly gave us has helped along with some help from others. so i think his is just an individual issue. as members get better they (I) will contribute more. the contest was great in that it high lighted a part of the program only a few has used a lot. i never would looked into it if not for the contest, perhaps that is a way to increase skill levels, by focusing on another part of tg....just my little rant
as an aside we have 3 forum members in denver colo - a lot for a world wide program
